(2) Sally starts eluting her column with petroleum ether in hopes of separating her 50:50 ferrocene: fluorenone mixture. She notices her mobile phase getting low when there is limited separation between her two components. She eagerly adds more solvent to avoid her column from drying out. Sally then realizes she poured from her 1:1 petroleum ether: diethyl ether beaker rather than her petroleum ether beaker. (a) Using the molecular view below, explain how this would impact her product elution from the column. top of column H buret wall AI H H H H H H H H H H bottom of column buret wall (b) How does this error impact her experimental results? (c) Using pictures and words, how could Sally analyze the purity of her product? Fe

The chemical method of analysis in determination of the blood alcohol content (%BAC) is: K2Cr2O7 + H2SO4 + C2H5OH → Cr2(SO4)3 + K2SO4 + CH3COOH + H2O What are the stoichiometric coefficients for the reaction above? (please enter the coefficients without spaces and with a coma between the numbers, e.g. 1,2,3,4) 2,8,3,2,2,3,11 During a Breathalyzer Test it was determined that 1.75mg of K2Cr2O7 was consumed by the above reaction. Calculate the number of milligrams of ethanol in the test sample. 0.411 Calculate the Blood Alcohol Content in this sample (%BAC).
